Multi-Server Redundant Install Guide¶

Overview¶

A multi-server redundant install is another install configuration used in production environments that require automatic failover for high availability. The usual configuration are two Presentation servers, two Database servers, two Elasticsearch Database servers, and two or more Collection servers, however, a single server can have one or more roles associated to it. This means that it is also possible to setup a combination Presentation/Database server and then one or more Collection servers, or a combination Presentation/Collection server with a separate Database server, etc.

See the Understanding Server Roles documentation for additional information around roles that are available.

Dependencies¶

See the Prerequisites for CentOS7 or RHEL7 documentation before starting an installation.

Best Practices¶

Adding a single server¶

When adding a single server to an environment that is using redundancy, the Database Watchdog service (Assure1 Database Watchdog Utility) must be manually enabled on the new server to ensure database connections are done to the correct destination server. This is done on the Services UI:

Configuration -> Broker Control -> Services

IP Failover using KeepAlived¶

If you are not using a physical load balancer for your Assure1 system, there is the option of using KeepAlived for load balancing based on virtual IP's.

KeepAlived is used for IP failover between two servers. It facilities for load balancing and high-availability for Linux based systems. It works using VRRP (Virtual Router Redundancy Protocol). The following example illustrates how to set up IP failover on your system using KeepAlived.

Note

If the presentation servers are in different subnets, or if a firewall between the servers is blocking multicast traffic, KeepAlived may need to be configured to use unicast instead of multicast. Additional information is available in the linux-admins.net Keepalived using unicast guide http://www.linux-admins.net/2015/02/keepalived-using-unicast-track-and.html.

Server Scenario¶

LB1 Server: - primary load balancer server
LB2 Server: - backup load balancer server
Virtual IP: - virtual IP address managed by KeepAlived

Installation¶

Install KeepAlived using the yum command:

yum install keepalived

On the primary server, edit the KeepAlived configuration file (/etc/keepalived/keepalived.conf). Replace the placeholder values with your Assure1 system and network configuration.

! Configuration File for keepalived

global_defs {
   notification_email {
     <TO_EMAIL_ADDRESS1>
     <TO_EMAIL_ADDRESS2>
   }
   notification_email_from <FROM_EMAIL_ADDRESS1>
   smtp_server <SMTP_SERVER>
   smtp_connect_timeout 30
}

vrrp_instance VI_1 {
    state MASTER
    interface <INTERFACE_NAME>
    virtual_router_id 51
    priority 101
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass 1111
    }
    virtual_ipaddress {
        <SHARED_IP_ADDRESS>
    }
}

On the backup server, edit the KeepAlived configuration file (/etc/keepalived/keepalived.conf). Replace the placeholder values with your Assure1 system and network configuration.
```
! Configuration File for keepalived

global_defs {
   notification_email {
     <TO_EMAIL_ADDRESS1>
     <TO_EMAIL_ADDRESS2>
   }
   notification_email_from <FROM_EMAIL_ADDRESS2>
   smtp_server <SMTP_SERVER>
   smtp_connect_timeout 30
}

vrrp_instance VI_1 {
    state MASTER
    interface <INTERFACE_NAME>
    virtual_router_id 51
    priority 100
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass 1111
    }
    virtual_ipaddress {
        <SHARED_IP_ADDRESS>
    }
}
```
- Make sure to set the priority value to a lower value than the primary server "priority" value (in this example, the primary server "priority" value is set to 101, while the backup server "priority" value is set to 100).
- virtual_router_id should be the same on both primary and backup servers.
Note

In the above example, email notifications are setup on KeepAlived changes. A Syslog option is also available, to send a Syslog message when a change is detected.
Start the KeepAlived service using the following command:

service keepalived start
Configure KeepAlived to automatically start on system boot up:

chkconfig keepalived on

By default, the virtual IP address will be assigned to primary server. In the event that the primary server goes down, the virtual IP will automatically be assigned to the backup server. The following command will show the assigned virtual IP on an interface:

ip addr show <INTERFACE_NAME>

Sample Output

2: <INTERFACE_NAME>:  mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 1000
    link/ether <MAC_ADDRESS> brd <NETMASK>:ff
    inet <PRIMARY_IP_ADDRESS>/24 brd <NETMASK>.255 scope global <INTERFACE_NAME>
    inet <SHARED_IP_ADDRESS>/32 scope global <INTERFACE_NAME>
    inet6 fe80::20c:29ff:fe6f:ed60/64 scope link
       valid_lft forever preferred_lft forever

Verifying IP Failover¶

Shut down the primary server and check if the IP address is automatically assigned to the backup server.

ip addr show <INTERFACE_NAME>
Next, start the primary server again and stop the backup server. Check to ensure that the IP address is automatically assigned to the primary server.

ip addr show <INTERFACE_NAME>

Examine the log file to ensure everything is working as it should.

tailf /var/log/messages

Sample Output

Mar 19 17:30:24 localhost Keepalived_vrrp[6958]: VRRP_Instance(VI_1) Transition to MASTER STATE
Mar 19 17:30:25 localhost Keepalived_vrrp[6958]: VRRP_Instance(VI_1) Entering MASTER STATE

Steps¶

Preparation¶

Get the collection files by logging into MOS, then going to the "Patches & Updates" tab.
Upload the files to the "/opt/install/" directory on the presentation servers that will be part of the environment. (Create the directory, if it does not already exist.)
Unzip all of the collection files:
```
unzip p#-part#of#.zip
```
Extract the contents of the collection to the /opt/install/ directory:
```
cat Assure1-5.X.Y-ZZZ.tgz.part-* | tar -C /opt/install/ -xzv
```
Upload the RPM file to the "/opt/install/" directory on all servers that will be part of the environment. (Create the directory, if it does not already exist.)
Install the RPM on all servers that will be part of the environment using one of the following examples.
- This will install Assure1 into the /opt/assure1/ directory:
```
yum install /opt/install/Assure1-5.X.Y-ZZZ.x86_64.rpm
```
- Assure1 can be installed to a different directory by using the "rpm" installation command with the "prefix" flag. An example is shown below which will place the files in the "/opt/a1/" directory:
  
  Warning
  
  Using the "rpm" command will not automatically install the required dependencies, and some dependency errors may come up if using this method. Install the missing dependencies, then install again using the "rpm" command.
```
rpm -ivh --prefix /opt/a1 /opt/install/Assure1-5.X.Y-ZZZ.x86_64.rpm
```

Base Installation¶

Primary Presentation Server¶

The SetupWizard for installing Assure1 is located in the $A1BASEDIR/bin/ directory. Go to the directory:
```
cd $A1BASEDIR/bin/
```
Note

The default $A1BASEDIR is /opt/assure1/. This may be different if a custom path was used in the preparation step.
Run the SetupWizard to begin the installation. The SetupWizard command must be run as root:
```
./SetupWizard --Depot /opt/install/:a1-local
```
When prompted Is this your Primary Presentation Server?, enter y and press Enter.
When prompted What is this install's Web FQDN? [FQDN]:, make a change if needed, then press Enter.
When prompted Comma-delimited list of roles to install (numeric):, enter the numerical values for the following roles, and then press Enter:
- Presentation
- Database.Redundancy
- Presentation.Redundancy
- Processing
  
  Note
  
  The "Processing" role is installed on the presentation server to split the overall load across the servers in the environment. While it is not required to be on the presentation server, it will still need to be installed on a server somewhere in the environment. If the applications run as part of this role become too much for the server, the role may need to be migrated to be on a dedicated system.
When prompted Do you accept all the license agreements? Must type "AGREE":, enter AGREE and press Enter.
The software will then be installed. Wait for this process to finish.
The following log files can be checked for errors that may have occurred during the install:
- $A1BASEDIR/logs/SetupWizard.log
- $A1BASEDIR/logs/Package.log
Enter the web-FQDN of the server into your browser to open up the UI login page. Login with:
- Username: admin
- Password: admin
Navigate to the Users UI and select the admin user account.

Configuration -> AAA -> Users

Note

As a best practice, it is advised to update/change the administrator password to a password of your choosing.
